How often should Mammograms be performed after a woman has Breast Cancer in one Breast?
A mammogram is recommended 6 months after lumpectomy and radiation therapy to serve as a new baseline. Subsequently annual mammograms should be performed. Mammography is helpful to detect the development of a new cancer in the other breast or the same breast. In a patient with mastectomy on one side, mammograms should be obtained annually on the other breast. There is a high risk of developing breast cancer in the normal breast for a woman who already had breast cancer in the other breast.
